IMPROVEMENT lN HYDRAULIC MAINS OF GAS-WORKS.

Specification forming part of Letters Patent No. 119,919, dated October17, 1871.

To all whom it may concern:

Be it known that I, CHARLES COLLIER, of the city of Selma, in the countyof Dallas and State of Alabama, have invented a certain new and usefulImprovement in Gas-Works for Safety in Charging the Retorts; and thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing making a part of thisspecification, in which- Figure 1 represents a sectional-View elevationof my improvements in gas-works, showing an additional pipe, dry-main,or receiver, and its connections with the'hydraulic main,cut-off valve,pipes, and retort.

The object and nature of my improvements are to relieve the pressure ofthe gas on the retorts, when being charged, by closing a valve connectedwith a dry-main or receiver and opening the same after it is charged,the whole being so constructed that it can be applied to any bench orbenches of retorts while the gas-works are in full operation. Myinvention consists of an additional dry-main pipe or receiver placed inthe rear of the hydraulic main, in general use in gas-works, andconnected with the said main by an arch-pipe provided with a stop-valveor cut-off, and also an additional valve placed beetween the receiverand the dip-pipe.

To enable others to make, apply, and use my improvements, I willdescribe them, referring to the drawing.

To a bench of retorts, A, set in brick-work B on which the hydraulicmain 0 is mountedin the vusual manner, with its dip-pipe D, bridge-pipeE, and stand-pipe F, all connected for operation, I place an additionalpipe-main or receiver, G, in

the rear of the hydraulic main, running parallel with it, at anysuitable or convenient distance apart, and connect the two mains G and Gtogether by an arch-pipe, H, having a T-pipe, h, to convey the gas fromthe retorts to the condenser, &c.; also providing it with a cut-off, g.The additional gas-main or receiver G is provided with a valve, I,placed anywhere in the pipe J, which connects the receiver Gr with thedippipe D, the valve I being operated by a rod, 1?, lever j, pendent 7c,and balance-weight m to counterbalance the weight n on the lever j, orany other suitable mechanical device.

The advantages of my improvements are that they can be applied to anygas-works, and the connections made therewith without the interferingwith or stopping the manufacture of gas.

Having thus fully described my improvements in gas-works, what I claimas my invention, and desire to secure by Letters Patent, is

l. The dry-main or receiver Gr and the archpipe 11, in combination withthe hydraulic main 0, substantially as herein shown and described.

2. In combination with the above, the valve I with its pipe-connectionsJ J with the dip-bridge and stand-pipe, the rods 1' k, lever j, andweights m and n, or their equivalents, for operating the same in themanner as and for the purposes here- 7 in set forth.

In testimony whereof I hereunto subscribe my name.

CHARLES COLLIER.
